ASSESSMENT OF WATER QUALITY POLLUTION INDEX FOR FISHING IN JIBIA DAM, KATSINA, NIGERIA

Abstract

The study aim to assess Water Quality Pollution Index for Fishing in Jibia Dam, Katsina State. Improper monitoring of level of water quality in the dam may lead to pollution of the water and the death of fish. Water samples were collected at ten points in the wet and dry seasons 2019/2020, i.e., ten sample stations, thirteen parameters were analyzed using standard laboratory techniques. The parameters include Temperature (T), pH, Electric Conductivity (EC), Total Dissolve Solid (TDS), Turbidity (Tur), Total Hardness (TH), Chloride (Cl), Nitrate (NO3), Dissolve Oxygen (DO), Biological Oxygen Demand (BOD), Ammonia (NH3), Nickel (Ni), and Lead (Pb). Based on findings metal pollution index, (Cd), and water pollution index (WPI) status were determined. Findings of the research show that the metal pollution index (MPI) of the parameters is pure except for Ni which is slightly affected. Contamination Index (Cd) all the parameters are low in contaminants except (BOD), which is medium, (TDS) and (NH₃) are higher contaminant indexes. For   Water Pollution Index (WPI); (Temp.), pH, (Tur.), (EC), (Ni) and (Pb) are rated as good water by status. (TDS), (DO), (BOD), and (NH₃) are unsuitable for fishing. (CL) and (NO₃) are excellent statutory. Total Hardness is the only poor statutory finding in the study area. It is recommended that effective fishing activity be carried out in the reservoir since the water meets the standards of fishing.
